My boys are 15 an 11 and we still give gifts from Santa. My oldest ds found out about Santa when he was 8 or 9 thanks to my MIL. We had returned from a trip to WDW where our son had seen a gap in a Mickey head and realized it was a costume. He was telling my MIL when we returned and she was shocked that he had believed that long and snarkingly said "don't tell me you still believe in Santa and the Easter bunny too?" She almost seemed pleased with herself for telling him and DH and I were ticked. My DH was raised Jewish and said that he always believed in Santa but his mom told him that Jewish kids didn't get presents from Santa. When we first started dating, my dh said once when he was little his boy scout troop saw Santa at the mall and he told him all he wanted was a Christmas tree and Santa was shocked and really didnt' know how to respond. Our younger son is a very critcal thinker and quizzed me from a young age about how one Santa could get gifts to every child, etc. I told him he had helpers, but he was still skeptical. They are both good sports about 'believing' for younger cousins.
